SPEAR-KNIFE.

Specification of Letters Patent.

Patented May 16, 1916.

Application filed February 18, 1915. Serial No. 9,173.

To all whom it may concern.'

Be it known that I, JACOB DARES, a citi- Zen of the United States,residing at Starbuck, in the county of Columbia and State oflVashington, have invented certain new and useful Improvements inSpear-Knives, of which the following is a specification.

This invention relates to improvements in spear knives and its object isto produce a device of this class adapted to securely inv pale the gameas soon as it is struck. Simplicity in construction and efficiency 1noperation are other objects.

lith the foregoing and other objects in view the invention consists inthe combination and arrangement of parts to be hereinafter fullydescribed in the following specification, pointed out in the claims andillustrated in the accompanying drawings which form a part of saidspecification and in which- Figure l is a plan view of the knife. Fig. 2is a longitudinal sectional view taken on line 2 2 of Fig. (l. Fig. 3 isa plan view of the device showing the method by which it securelyimpales the prey. Fig. l is a section taken on line 4% of Fig. 2. Fig. 5is a section taken on line 5 5 of Fig. 2. Fig. 6 is an edge view of Fig1.

Like reference characters indicate corresponding parts throughout theseveral views.

The reference numeral 1 designates the handle to which a casting 2 issecured thatl is formed with oppositely disposed ears 3, 3. The handleis projected to form a casing l provided with a partition 5 throughwhich a. shank (3 extends that also passes through the casing l and isprovided with a shoulder 7 disposed within the casing and upon which oneend of a spring 8 rests which spring also abuts the partition 5. Theshank 6 beyond the casing 4 is bifurcated and carries a pin 9 upon whicha disk 10 is mounted which frictionally engages the periphery of anapproximately semi-circular jaw 11 which is recessed at 11a to receivesaid disk and is arranged upon a pivot 12 carried in the longitudinallyslotted portion 13 of the blade 14; said blade being further formed withan eye 15 and with a pointed termination 16.

The normal position of the jaw 11 is clearly shown in Figs. 1 and 2 andthel purpose, of the disk 1() is to frictionally retain the jaw in suchposition, pressure upon the disk Leing afforded through the medium ofthe spring 8.

The knife thrown or hurled at the game and when it strikes the same thepointed end of the blade enters the flesh until the fiesh strikes thejaw 11 at its lowest point thus swinging said jaw upon its pivot,against t-he tension of the disk .10, and forcing the point of this jawalso into the tiesh impaling the game between said jaw and blade in themanner illustrated in Fig. 3.

To release the game from the knife the jaw is manually forced back intooriginal position and the blade withdrawn.

To use asa harpoon the ears 3, 3 will serve to secure the ends of thecord.

lVhat is claimed is:

1. A spear knife comprising a handle, a blade made integral therewith, acurved jaw pivotally associated with said blade and. means carried bysaid handle for frictional engagement with said jaw whereby the same isyieldingly retained in normal position.

2. A spear knife comprising a handle. a blade made integral therewith.a. curved re cessed jaw pivotally associated with said blade and aspring-pressed friction .roller carried by said handle normally inengagement with the recessed portion of said jaw to yieldingly retainthe same in normal position.

3. A spear knife comprising a handle. a blade integral therewith. acurved `jaw pivotally associated with said blade and means operativelyassociated with said blade and jaw whereby they are yieldingly retainedin fixed relation with each other.

el. A spear knife comprising a handle, a longitudinally slottedblademade integral therewith` a curved jaw pivotally disposed in theslotted portion of said blade and means operatively associated with.said blade and'jaw whereby they are yieldingly retained in fixedrelation with each other.

A spear knife comprising a handle` a longitudinally slotted blade formedwith an eye and formed integral with said hars elle, a curved jawpivotally disposed in the as my own I have hereto aiixed my signaslottedportion of said blade and capable ture in the presence of twosubscribing Witof cooperation with the eye in said blade nesses. andmeans operatively associated with said JACOB OAKES. 5 blade and jawwhereby they are yieldingly Witnesses:

retained in fixed relation with each other. J. J ZINK,

In testimony that I claim the foregoing D. C. GUERNSEY.
